How to Fertilize Greenhouse Soil and Add Organic Fertilizer
Organic fertilizer contains various nutrients required by fruits and vegetables and contains a large amount of microorganisms, but the amount of nitrogen-containing organic fertilizer should be moderate. The amount of nitrogen fertilizer used should be moderate, and the top dressing should be “a small number of times†and watered after application. For soils that have already undergone acidification, methods such as spraying lime and neutralizing acidified soils in acid soils should be adopted. When the greenhouses are cultivated for many years and the soil salinization and acidification are serious, the soil in the tillage layer must be replaced in time and the fertile soil should be replaced in the greenhouse.
